CVS is the popular version control system in the free software
community, used by *BSD, many Linux projects, Netscape and others

CVS is the Concurrent Versions System, the dominant open-source network-transparent version control system. CVS is useful for everyone from
individual developers to large, distributed teams:
-Its client-server access method lets developers access the latest code from anywhere there's an Internet connection.
-Its unreserved check-out model to version control avoids artificial conflicts common with the exclusive check-out model.
-Its client tools are available on most popular platforms.
CVS is used by popular open-source projects like Mozilla, the GIMP, XEmacs, KDE, and GNOME.
-Relig museum and Cult heritage -
are other examples of using CVS for web programming and authoring.

The book "A Practical Guide to Linux" includes 15+ pages on CVS and
material about RCS, GCC, Emacs, vi and other programs. Linus Torvalds
learned unix from one of "Mark Sobell's other books", and "A Practical Guide to Linux"
is suitable either for starting with linux/unix or for reference.

Cyclic opposes government restrictions on encryption technology. Such
restrictions make it hard to develop programs, such as CVS, which
communicate over computer networks. CVS was used to
develop the software in the DES
Cracker project to investigate the strength of the DES encryption
standard.
